A museum has been offered an undocumented statue.supposedly Greek and from the sixth century B.C.Possibly the statue is genuine but undocumented because it was recently unearthed or because it has been privately owned.However, an ancient surface usually has uneven weathering, whereas the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface.Therefore, the statue is probably a forgery.
Which of the following, if true, most seriously weakens the argument?
A museum has been offered an undocumented statue, supposedly Greek and from the sixth century B.C. Possibly the statue is genuine but undocumented because it was recently unearthed or because it has been privately owned. However, an ancient surface usually has uneven weathering, whereas the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface. Therefore, the statue is probably a forgery.
which of the following, if true, most seriously weakens the argument?
(A) Museums can accept a recently unearthed statue only with valid export documentation from its country of origin. (B) The subject’s pose and other aspects of the subject’s treatment exhibit all the most common features of Greek statues of the sixth century B.C. (C) The chemical bath that forgers use was at one time used by dealers and collectors to remove the splotchy surface appearance of genuinely ancient sculptures (D) Museum officials believe that forgers have no technique that can convincingly simulate the patchy weathering characteristic of the surfaces of ancient sculptures.C (E) An allegedly Roman sculpture with a uniform surface similar to that of the stature being offered to the museum was recently shown to be a forgery.
这个题是这样的..原文有一个现象.. the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface..这是一个客观的事实..首先明确事实是不能被削弱的.. 对于这个事实..原文的结论是. Therefore, the statue is probably a forgery..这也是对这个事实的一种解释..不知道LZ能绕过这个弯不?能的话我就直接说了.这是一篇现象解释文..在削弱题中的正解就是另外一个合理的解释..也就是C..它是the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface..这个现象的另外一个合理解释..
换常规说法..削弱题的本质是论据对结论不一定对...也就是说原文的论据the surface of this statue has the uniform quality characteristically produced by a chemical bath used by forgers to imitate a weathered surface成立!!但是我们推不出结论..C就是这么个信息..告诉我们论据成立也可能是因为..dealers and collectors to remove the splotchy surface appearance of genuinely ancient sculptures..从而结论一定不成立..C符合正解特征..
